debugging

问题 The following C# program (built with csc hello.cs ) prints just Hello via Console! on the console and Hello via OutputDebugString in the DebugView window. However, I cannot see either of the System.Diagnostics.* calls. Why is that? using System; using System.Runtime.InteropServices; class Hello { [DllImport("kernel32.dll", CharSet=CharSet.Auto)] public static extern void OutputDebugString(string message); static void Main() { Console.Write( "Hello via Console!" ); System.Diagnostics.Debug

问题 I am working with Python 3.6.2 and Bokeh 1.0.4 to create a custom JavaScript callback in my plot. By tapping on one of the points in the plot, I'd like all points sharing the same attribute in the id-column to be highlighted. Iterating over all datapoints with JavaScript and manipulating the respective 'selected'-attribute in the ColumnDataSource-object should do the trick. Unfortunately I can not figure out how to correct this code. # Import packages from bokeh.plotting import figure, show

问题 I've spent two days on this and I still can't find the cause of the crash. I know it has something to do with trying to access an object that has been freed but I don't know which access or which object. Whenever I google trying to find the source of EXC_BAD_ACCESS people suggest using NSZombies.
